Domestic Medium Hair is a coat description, not a breed. It covers mixed-ancestry house cats whose fur falls between short and long: fluffier than a domestic shorthair, often with a plumed tail, tufts between the toes and a soft undercoat, but without a heavy ruff. They appear in every color and pattern, from tabby and tuxedo to calico and solid black.
Size, personality and health follow each cat rather than a breed standard. Most weigh 6 to 14 pounds, live 12 to 18 years and are sturdy. In Aurora, where winters keep cats indoors for months, the undercoat tends to shed visibly, especially in spring and fall, so a brush and a lint roller become household tools. Meeting the cat is the best guide to temperament.
